A Guide to Write a Clean Code in Java Assignment

Java is an object-oriented programming language which is used by many large scale industries for their applications. Here we will discuss the guidance you need to write clean codes in your javas assignment. Basically, well-written programs are easier to debug, easier to maintain, and have fewer errors. So one needs to have good knowledge of java to score good marks.

  • The first letter should be the capital of every method, Variables, etc.
  • The capital letter must be applied in constants with using underscore
  • Ignore special characters and numbers
  • Avoid using so many words in the variable, use some informative words, and try to make it simple.


A good Programmer always comments on their codes. It helps them to understand the procedure of their program. A code defines computer and programmer ‘what is being done’ while comments describe programmer ‘why it’s being done.’ Moreover, the debugging process of code is done by using comments. So the comments play a vital role in java assignments and help other programmers understand it better.

Minimize class size

We should minimize the class size to make the code simpler. A good programmer uses simple codes because simpler codes result in faster execution and take less run time. As per the actual lines of code per class, every programmer has a personal recommendation. According to some of them, the class must not be larger than 900 lines of code, whereas some believe that 2000 is the highest limit.

Use Java-style conventions

Test runs importance

Why take risks with error messages? We recommend you to run the code after writing. It allows you to self-check code, whether it is working or not, making your code clean.

If it seems tough for you, then you can also install some plugins in your development environment.

Best practices
